Poly(1-vinylpyrrolidone-co-vinyl acetate) ni yo mavuta y’ingenzi akoreshwa mu kwisiga akoreshwa mu gukora gel y’umusatsi, mousse, shampoo, nibindi, ndetse no mu gukora surfactants, imiti n’ibindi bikorwa by’inganda. Akoreshwa cyane cyane nk’amabati ashongeshwa n’amazi n’amabati yumye mu ikoranabuhanga rya granulation na direct tableting, nk’ibikoresho byo gukora filime mu gutwikira filime, no nk’ibintu bikora imyenge mu bikoresho byo gupfuka. PVP va64 ikoreshwa mu gutwikira isukari kugira ngo idacika. Igitambaro cyo hasi gikoreshwa mu bikorwa byo kwirinda ubushuhe. PVP va copolymer mu kwisiga, Ibicuruzwa bya Vp/va copolymer bikoreshwa cyane cyane nk’ibikoresho byo gukora filime n’ibikoresho byo gutunganya imiterere mu bijyanye n’ubwiza, cyane cyane mu bikoresho byo gutwika, gel y’umusatsi, mousse n’ibicuruzwa bya shampoo. Bigira uruhare runini nk’ibikoresho byo gukora filime n’ibikoresho byo gutunganya umusatsi. Iyo bikoreshejwe hamwe napvp k30, ingaruka zo gukoresha kwazo zizongera kwiyongera.
